Prof. Dr. Falko Dressler, Head of the Distributed Embedded Systems Group at the Universität Paderborn, will give a presentation on "From Connected Cars to Virtual Edge Computing to Cooperative Driving" referieren. The presentation takes place on 14 March 2019 at 4 p.m.

Abstract:

We discuss the challenges and opportunities of the connected cars vision in relation to the need for distributed data management solutions ranging from the vehicle to the mobile edge and to the data centers. Vehicular networking solutions have been investigated for more than a decade but recent standardization efforts just enable a broad use of this technology to build large scale Intelligent Transportation Systems. As a novel concept, vehicle micro clouds have been proposed that bridge the gap between fully distributed vehicular networks based on short range device to device communication and 4G+ based infrastructure for centralized solutions. We also shed light on the potentials of a vehicular cloud based on parked vehicles as a spatio-temporal network and storage infrastructure. Using platooning as a selected application example, we assess the needs on the underlying system components with a particular focus on inter-vehicle communication. Overall, it turned out that vehicular networks are way more dynamic than originally considered. Radio signal fading and shadowing effects need to be considered in the entire design process as well as the strong need for low-latency communication, fairness, and robustness. We bring all these aspects together outlining necessary ingredients for future cooperative driving solutions.

Presentation by Prof. Dr. Peter Vortisch (KIT) "Evolution or Revolution? - The Pace of Change in Mobility” on 31 January 2019 at 3.30 p.m.

Prof. Dr. Peter Vortisch, Head of the Institute for Transport Studies at Karlsruhe Institute of Technology, will give a talk on "Evolution or Revolution? - The Pace of Change in Mobility". The talk is scheduled to take place on 31 January 2019 at 3.30 p.m.

Abstract:

If you listen to people talking about mobility, quite often “disruptive” innovations are seen at the horizon, most prominent of all automated and autonomous driving. Other major changes are expected from more communication (C2C, C2X) or from changed behavior (“sharing economy”). In my talk, I will show how fast the system of mobility has changed in the past, and how fast I expect it to react on these new “disruptive” developments. My reasoning will be based on travel behavior research, i.e. an analysis of who travels by which means of transport and to which purposes. We will see that the mobility system has some components leading to high inertia, so that even disruptive technical developments will only slowly change the whole situation.

Dr. Alexandra Millonig from the Austrian Institute of Technology gives a presentation on "How autonomous vehicles may change our mobility behaviour". The presentation takes place on 22 November 2018 at 4 p.m.

Abstract:

Decades ago, self-driving cars have already been envisioned as a desirable future, promising higher safety and better use of travel time. Now, as we are on the edge of making this vision reality, the image becomes blurry and the actual impact of automation on the future of mobility is intensively debated. Studies developing different scenarios show very controversial potential transformation paths, as the way automation is going to shape our future is mainly depending on how we are going to use this new technology – resulting in future scenarios ranging from high-tech visions of future societies being constantly on the move to automation basically serving as fill-in to complement gaps in a transport system focusing on active mobility and mass transport.

Based on existing findings on the characteristics and needs of different social groups as well as discoveries from behaviour research, this contribution will discuss the potential impact of automated vehicles from a mobility behaviour research perspective and how these new concepts may influence the change of mobility patterns in the future. The results will highlight the main advantages and limitations of novel mobility concepts for societal developments.

Prof. Jörg-Rüdiger Sack (School of Computer Science, Carleton University, Ottawa) will give a talk on "Approximating Weighted Shortest Paths in 2/2.5/3-d". The talk is scheduled to take place on 25 October 2018 at 2.30 p.m.

Abstract:

Shortest path problems are among the fundamental problems studied in graph theory and computational geometry. Practical problems arise in applications areas such as robotics, traffic control, search and rescue, water flow analysis, road design, navigation, routing, geographical information systems. Most of these applications demand simple and efficient algorithms to compute approximate shortest paths as opposed to a complex algorithm that computes an exact path.Motivated by the practical importance of these problems and very high complexities for computing exact shortest paths (in particular in weighted scenarios or in 3D) we investigate algorithms for computing approximated shortest paths. In this talk we describe several simple and practical algorithms (schemes) to compute an approximated weighted (and unweighted) shortest path between two points on the surface of a (possibly, non-convex) polyhedron (or a TIN).We also describe ϵ-approxmiation algorithms for such problems. While these algorihtms have a more complex analysis their implementation remains simple. Furthermore, we sketch our work on shortest anisotropic paths on terrains. Anisotropic path costs take into account the length of the path traveled, possibly weighted, and the direction of travel along the faces of the terrain. Considering faces to be weighted has added realism to the study of (pure) Euclidean shortest paths. Parameters such as the varied nature of the terrain, friction, or slope of each face, can be captured via face weights. Anisotropic paths add further realism by taking into consideration the direction of travel on each face thereby e.g., eliminating paths that are too steep for vehicles to travel and preventing the vehicles from turning over.Finally, we discuss some very recent developments in computing shortest paths in 2-D and 3-D
